Rain....Water vapor condenses as it goes up into the sky becuase the atomospher gets cooler and cooler as we go up. When the vapor condenses it forms "rain clouds." As the vapor builds up the pressure becomes so great that the water falls back to earth as rain.

There are many examples.
Liquid nitrogen, used for cryogenics, is one example. Nitrogen gas is compressed to high pressure until it become liquid. The liquid nitrogen is then stored in a tank to keep it in liquid form.
Another, more common example, is carbon dioxide. CO2 is used in welding and in equipment such as paintball guns and bb guns. The CO2 (what we exhale when we breathe) is more easily compressed into a liquid and stored in tanks at a lower pressure than nitrogen.
Hope this helps.

Rain. It starts as water vapor or water in gas form in the air. It condenses in the colder air higher up in the atmosphere and becomes rain water.

just put a pot containing water on the cooker and close it's cover and then wait for a while. After that when you remove the cover you see it's wet, that's because the vapor which was generalized from the water was condensed again to water.
